cheddar: Analysis and Visualisation of Ecological Communities

Provides a flexible, extendable representation of an ecological community and a range of functions for analysis and visualisation, focusing on food web, body mass and numerical abundance data. Allows inter-web comparisons such as examining changes in community structure over environmental, temporal or spatial gradients.

Authors:Lawrence Hudson with contributions from Dan Reuman and Rob Emerson
